A car has a mass of 1000 kilogram it's at the top of a 10o hill. Therefore if you were to draw a triangle the base of the triangle would be 50 meter in length as well.
a. Find what is it gravitational potential energy relative to the bottom of the hill?b. If the car rolls down the hill with (the engine off) with negligible friction and air resistance determine what will its kinetic energy be when it reaches the bottom?
